Description:FIELD OF THE INVENTION

[0001] The present invention relates to a crop protection device for hilly areas that is capable of identifying and reacting to animal presence and other external threats with precision and speed in vicinity of crops grown in the hilly areas fields, thus preventing the crops from getting damaged by animals and external threats.

BACKGROUND OF THE INVENTION

[0002] In recent years, the cultivation of crops in hilly and mountainous terrains has become increasingly significant due to growing population demands and the expansion of agricultural practices into less conventional areas. However, these regions present unique challenges that differ greatly from those encountered in flat agricultural lands. The irregular topography, susceptibility to landslides, frequent animal intrusions, and unpredictable weather patterns such as heavy rainfall and strong winds make it difficult for farmers to ensure the safety and productivity of their crops. Additionally, the risk of erosion and soil displacement further complicates the long-term sustainability of agricultural activity in such environments.

[0003] Traditional methods of crop protection, including simple fencing or manual monitoring, often prove ineffective or impractical in these challenging landscapes. Inaccessibility and the lack of strong means further hinder efficient field management. Furthermore, threats from wild herbivores and predators in forest-adjacent hilly zones often result in significant crop damage, making it critical to develop a means capable of detecting and responding to such threats in real time.

[0004] Moreover, environmental elements such as falling rocks during seismic disturbances and dust or debris carried by strong winds severely affect crop quality and yield. In the absence of responsive technologies that mitigate these risks, farmers face economic losses and increased labor burdens.

[0005] US20160286785A1 discloses about an invention that has an animal deterrent includes a housing having a high voltage spark generator disposed within. A power source, such as a battery, is connected to the high voltage spark generator. A sensor may be connected to the battery and is operable to detect at least one of a motion and a sound. When the sensor detects at least one of the motion and the sound, the power source powers the high voltage spark generator so that the high voltage spark generator generates high voltage sparks. The high voltage sparks produce a sound and a light, along with ozone scaring animals away.

[0006] US20060174533A1 discloses about an invention that has an animal repellant system which includes triggering means for detecting the presence of animals within a particular area and generating signals indicative thereof. The animal repellant system includes a controller operable to receive the signals generated by the triggering means and to issue command signals responsive thereto, and deterrent means for effectuating a repellant component of the animal repellant system in response to the command signals issued by the controller, thereby dissuading the animals from entering the particular area.

[0007] Conventionally, many means are available for protecting crops in hilly areas. However, the cited invention lacks in enabling real-time identification of animal threats for timely and appropriate deterrent actions. Also, the cited arts are incapable of ensuring the safety and preservation of crops during seismic activity to shield the cultivation area from falling debris.

[0008] In order to overcome the aforementioned drawbacks, there exists a need in the art to develop a device that requires to be capable of operating autonomously and addressing the multifaceted risks associated with farming in hilly terrains. Such a device would not only preserve the integrity of crops but also support the livelihoods of farmers operating in these difficult geographical regions.

SUMMARY OF THE INVENTION

[0019] The present invention relates to a crop protection device for hilly areas that safeguard crops in hilly regions and offering comprehensive defense against environmental threats and animal intrusions.

[0020] According to an embodiment of the present invention, a crop protection device for hilly areas, comprising a set of hydraulic bodies installed at the corners of a hilly agricultural field. These bodies are interconnected via a collapsible net formed from a plurality of links arranged in a crisscross configuration. The links are initially stored in a stowed state and are connected via pin joints that enable movement towards and away from each other. Upon detection of a threat, the net is deployed to form a protective perimeter around the field. Each hydraulic body is equipped with a thermal imaging sensor paired with an electronic nose, collectively used to detect the presence of animals based on body heat and odor signatures. These sensors are interfaced with a microcontroller, which is linked to a database for identifying the type of approaching animal. If the animal is identified as a predator or herbivore, the microcontroller activates a hydraulic unit within the body to extend and deploy the net by moving the links outward to form a physical barrier.

[0021] The hydraulic bodies include speakers controlled by the microcontroller that emit deterrent sounds at frequencies specifically selected based on the type of animal detected to effectively scare it away. To address geological risks, seismic sensors are also integrated with the bodies to detect vibrations in the ground. Upon detection of seismic activity, the microcontroller actuates a motorized hinge positioned at the apex of each hydraulic body, enabling the deployment of triangular-shaped members between adjacent bodies. These members are composed of a first and second layer joined by a plurality of springs, providing structural protection and shock absorption from falling rocks or debris.

[0022] One of the hydraulic bodies includes an L-shaped rod connected to a hydraulic shaft through a sun and planetary gear arrangement. A robotic arm mounted on one of the bodies retrieves a soil anchor from a chamber mounted on the body. The anchor is engaged with a motorized clamp on the shaft. For managing rainfall, a set of V-shaped units are installed between adjacent hydraulic bodies. A rain sensor on one of the bodies detects precipitation and signals the microcontroller, which then actuates a motorized pivot joint to tilt the V-shaped units. This prevents water accumulation on the triangular members and facilitates efficient drainage. An additional environmental deterrent is provided by a multi-sectioned container mounted on one of the bodies.

[0023] Each section contains a different fragrance solution and is paired with an electronic nozzle capable of multi-directional spray via a motorized swivel joint. Based on the type of animal identified, the microcontroller activates the appropriate nozzle to disperse a specific fragrance in the surroundings to repel the intruder. To further enhance crop protection, a dust sensor on each body detects airborne dust levels. If high levels are detected, the microcontroller activates an electrostatic generation unit configured on each link of the collapsible net, energizing the net with electrostatic charge to trap dust particles and prevent them from entering the field. All the components of the device are powered by a battery, which supplies electricity to the various electronically and electrically operated components integrated into the device.

[0024] While the invention has been described and shown with particular reference to the preferred embodiment, it will be apparent that variations might be possible that would fall within the scope of the present invention.

[0029] The present invention relates to a crop protection device for hilly areas that support healthier crop environments by reducing exposure to disruptive factors such as dust, wildlife, and excess rainwater, thereby preventing crops from damaging.

[0030] Referring to Figure 1, an isometric view of a crop protection device for hilly areas is illustrated, comprising a set of hydraulic bodies 101 installed at corners of an agricultural field in a hilly area, adjacent bodies 101 are connected with each other via a collapsible net 102, a thermal imaging sensor 103 configured on each of the bodies 101, a plurality of speakers 104 installed with the bodies 101, a triangular shaped members 105 configured between adjacent bodies 101, each of the members 105 is constructed with a first and second layer interconnected with each other via a plurality of springs 106, an L-shaped rod 107 configured with one of the bodies 101 and installed with a hydraulic shaft 108 via a sun and planetary gear arrangement 109, a robotic arm 110 configured on the body 101 for access a chamber 111 attached with the body 101, a motorized clamp 112 equipped with the shaft 108, a set of V-shaped units 113 installed between adjacent bodies 101, a motorized pivot joint 114 configured between the units and each of the bodies 101, a multi-sectioned container 115 is mounted on one of the bodies 101 and having each section configured with an electronic nozzle 116, each of the nozzle 116 is configured with a motorized swivel joint 117 and an electrostatic generation unit 118 configured with each of the net 102.

[0031] The device disclosed herein includes a set of hydraulic bodies 101 that are positioned at the corners of an agricultural field located in a hilly area. These hydraulic bodies 101 serve as the primary structural units and are responsible for enabling the deployment and retraction of a protective barrier around the cultivated land. Each body 101 is firmly mounted to the ground and is developed to operate under challenging environmental and terrain conditions typical of sloped agricultural zones.

[0032] The hydraulic bodies 101 are interconnected through a collapsible net 102 that extends between adjacent bodies 101. This net 102 acts as a physical barrier to prevent unauthorized or harmful entry into the field, particularly from animals. The net 102 is constructed from a plurality of interconnected links, each fabricated from durable and lightweight material suitable for withstanding tensile stress while allowing flexibility. These links are arranged in a crisscross configuration, creating a lattice-like structure that uniformly distribute force and maximize coverage when fully deployed. The crisscross arrangement not only strengthens the net 102 structure but also enables it to fold or unfold efficiently during its operation cycle.

[0033] In its default state, the net 102 remains stowed that ensures that the barrier remains unobtrusive and does not interfere with regular agricultural activities when no threat is detected. When the device is activated, typically in response to detected movement or the presence of animals, the hydraulic means within the bodies 101 initiates the extension process. The deployment process involves the outward movement of the interconnected links, facilitated by hydraulic actuators or pistons embedded within each body 101.

[0034] The links are connected using pin joints, which allow a range of motion between adjacent links. These joints enable the links to pivot with respect to one another, allowing smooth unfolding of the net 102 structure and precise alignment along the field's perimeter. As the hydraulic force pushes the links outward, the net 102 expands laterally and vertically, forming a continuous barrier that stretches from one corner body 101 to the next, thus effectively covering the open sides of the field.

[0035] The design of the net 102 and its link-joint configuration also provides the capability for controlled retraction. When the threat subsides or upon receiving a command from an inbuilt microcontroller, the hydraulic means reverses its action, drawing the net 102 back into the stowed configuration with minimal manual intervention. Each hydraulic body 101 is equipped with a thermal imaging sensor 103 paired with an electronic nose, working together to detect the presence of animals in the vicinity of the agricultural field. Positioned at an optimal height and orientation on each body 101, these sensors are continuously active and scan the surrounding area for thermal and olfactory cues that indicate the approach of an animal.

[0036] The thermal imaging sensor 103 operates by detecting infrared radiation emitted by warm-blooded organisms. Every animal emits heat from its body, and this heat contrasts with the cooler background environment, especially in outdoor, natural settings like hilly terrain. The thermal sensor captures this radiation and converts it into a two-dimensional thermal image or a set of thermal data points. This allows the microcontroller to identify not only the presence of an animal but also its size, shape, movement pattern, and distance from the field. For example, a small and fast-moving thermal signature correspond to a rabbit, while a larger, slow-moving heat source corresponds to a cow, wild boar, or even an elephant in regions where such animals are common.

[0037] Complementing the thermal sensor is the electronic nose to detect and analyze volatile organic compounds (VOCs) emitted by animals. These compounds are typically found in the body odor, sweat, urine, and breath of animals. The electronic nose consists of an array of chemical sensors that react differently to various odor molecules. When air from the surrounding environment passes through the sensor array, each sensor produces a signal that corresponds to the concentration and type of VOCs detected. The unique pattern of responses from the sensor array acts as an olfactory fingerprint for specific animals.

[0038] Both the thermal sensor and electronic nose are electronically linked to an onboard microcontroller integrated within each hydraulic body 101. Once data is received from the thermal sensor and electronic nose, the microcontroller executes signal processing protocols to interpret the information. The microcontroller then compares the collected data with entries in a preloaded database, which is either stored locally or wirelessly connected to an external cloud-based repository. This database contains a catalog of known animal profiles, including corresponding heat signatures, movement patterns, and VOC profiles for a variety of animal species that are typically found in or near the farmland.

[0039] For example, if the imaging sensor 103 and e nose detects a large heat signature accompanied by VOCs characteristic of a wild boar, the microcontroller classify the animal accordingly. On the other hand, a distinctly different combination of lower body heat and a unique scent profile indicate the presence of a deer or a goat. The microcontroller even differentiates between predatory animals (e.g., foxes, jackals, or wolves) and herbivores (e.g., cows, antelope, or wild pigs) based on historical data and pattern recognition.

[0040] Once the microcontroller identifies the type of animal, it initiates the appropriate response, such as activating the hydraulic deployment of the net 102. Importantly, the use of both heat and odor as detection modalities ensures higher accuracy and reduced false positives, especially in complex outdoor environments where visual recognition is less reliable due to poor lighting, fog, or vegetation cover.

[0041] Herein, a hydraulic unit is integrated within each of the hydraulic bodies 101 positioned around the perimeter of the agricultural field. This hydraulic unit is developed to operate with high force and precision for ensuring reliable performance even in the challenging and uneven terrain of hilly regions, including areas practicing step farming or terraced cultivation. These regions typically involve segmented levels of flat land carved into slopes, where the boundary of each cultivated platform is exposed to threats from wild or domestic animals that move freely between elevations. Traditional fencing methods in such topographies are often ineffective due to the irregularities in land levels and difficulty in achieving uniform protection.

[0042] When the microcontroller determines through thermal and olfactory sensing that a predator (e.g., jackal, fox, or stray dog) or herbivore (e.g., goat, wild boar, or cow) is approaching the field, it sends a signal to the hydraulic unit installed within the nearest or all hydraulic bodies 101 in the detection zone. This signal initiates the extension means, which prompts the hydraulic pistons or actuators to activate. These actuators are responsible for mechanically extending the collapsible net 102 stored between the bodies 101. The force generated by the hydraulic unit ensures that the net 102, which comprises a crisscross arrangement of interlinked elements, is pulled or pushed outward from its compact, stowed position.

[0043] The extension process involves a coordinated movement of the links that make up the collapsible net 102. These links are designed to slide or pivot away from each other, creating a strong and flexible barrier. A pin joints is a link that connect each segment of the net 102 to its adjacent segments. These pin joints are developed to allow rotational and linear motion, granting the net 102 a certain degree of elasticity and flexibility during deployment. When actuated by hydraulic pressure, the links swing outwards from their folded positions, gradually forming a continuous, web-like boundary along the edges of the field.

[0044] This boundary, once fully extended, serves multiple purposes. First and foremost, it acts as a physical deterrent, preventing animals from stepping into the cultivated area. The height and density of the net 102 varied depending on the target species, lower net 102 for small herbivores like rabbits or porcupines, and higher ones for larger animals such as cattle or deer. In hilly terrains, where conventional fencing is compromised by slope angles and erosion, the ability of the hydraulic unit to adaptively deploy the net 102 along the contours of the land ensures that no exposed edges are left vulnerable.

[0045] Consider an example of a step farming field located on a hillside, where each terrace is about 1–2 meters above or below the next. A traditional fence requires different elevations of posts and careful alignment, which is labor-intensive and prone to failure. In contrast, the present invention’s hydraulic bodies 101 remain grounded on each terrace corner, and upon detection of an animal climbing from a lower terrace, the hydraulic units instantly deploy the net 102 to form a vertical and horizontal barrier that stretches across the edge, matching the natural incline or decline of the slope.

[0046] In addition to the physical boundary provided by the collapsible net 102, the bodies 101 also comprise of a non-physical deterrent means in the form of a plurality of speakers 104 installed on each of the hydraulic bodies 101 surrounding the agricultural field. These speakers 104 emit sound waves specifically tuned to deter different types of animals identified by the thermal imaging sensor 103 and the electronic nose. Once the microcontroller classifies the animal approaching the field whether it’s a predator like a jackal or fox, or a herbivore such as a deer, boar, or cow, it initiates an auditory deterrent sequence. Each speaker 104 receives a signal instructing it to generate a customized sound output designed to be unpleasant, startling, or disorienting to that particular species. The frequency, volume, duration, and modulation of the emitted sound are all adapted based on the species detected.

[0047] Different animals have different auditory sensitivity ranges, meaning they perceive sounds in specific frequency bands. For example, dogs, foxes, and jackals hear high-pitched ultrasonic frequencies that are above the range of human hearing (above 20 kHz). On detecting such animals, the speakers 104 emit ultrasonic pulses or bursts that are barely audible or completely inaudible to humans but highly irritating to the targeted animal. These sounds cause discomfort, trigger an instinctual fear response, or interfere with the animal’s natural echolocation or communication abilities, prompting them to retreat from the area.

[0048] In contrast, larger herbivores such as cows, wild boars, or deer have hearing capabilities more attuned to mid-range frequencies. For these species, the speakers 104 emit low-frequency growls, predator noises, or synthetic distress calls that mimic the presence of a predator or suggest danger in the vicinity. For example, the speakers 104 emit replicate the sound of a tiger’s low growl or the hissing of snakes, both of which are natural deterrents to many herbivores. The microcontroller, by accessing its internal database and using the data received from the sensors, determines the best sound profile to deploy for each species.

[0049] To ensure maximum field coverage, the speakers 104 are positioned around each hydraulic body 101, allowing for 360-degree sound projection. In steep or terraced farming areas, this configuration ensures that animals approaching from lower slopes, upper ridges, or side paths are equally exposed to the deterrent sounds. Furthermore, the speakers 104 work in synchronization with each other, creating sound pulses that travel in waves, thereby enhancing the psychological impact of the deterrent.

[0050] Consider an example of a wild boars approaching the edge of a step farm. As soon as the sensor detects them, the speakers 104 are activated to emit sharp, rhythmic growls interspersed with high-pitched shrieks resembling predator calls. If the boars linger or approach further, the sound volume and frequency escalate in intensity, simulating a territorial defense scenario and convincing the animals that they are encroaching on a hostile area.

[0051] Importantly, the device is developed avoid habituation, a phenomenon where animals become desensitized to a repeated stimulus. To achieve this, the microcontroller rotates between different sound patterns for the same type of animal or vary the intervals at which the deterrent is applied. This response prevents the animals from adapting to the sound over time and ensures the continued effectiveness of the deterrent.

[0052] A plurality of seismic sensors configured within the hydraulic bodies 101 positioned at the corners of the agricultural field. These seismic sensors are highly sensitive instruments designed to detect ground-level vibrations that signal earthquakes, tremors, or landslides, which are frequent occurrences in hilly and mountainous terrains. Unlike flatlands, agricultural fields in these elevated regions are often situated along fault lines or unstable slopes, where even minor tremors dislodge rocks, debris, or soil masses that pose a direct threat to crops and farming infrastructure.

[0053] Upon detecting such seismic activity, these sensors immediately transmit a signal to the central microcontroller that rapidly assesses the vibration’s intensity and source. If the intensity exceeds a predefined threshold, the microcontroller initiates an emergency protection protocol by activating a motorized hinge installed at the apex portion of each hydraulic body 101. This hinge aids in deploying triangular-shaped protective members 105 that are flexible but strong canopies or shield-like structures that are cleverly stowed in a retracted position between adjacent bodies 101 during normal operation.

[0054] The triangular members 105 are specifically developed to tilt outward and unfold when actuated, thereby extending overhead and connecting with their corresponding units from neighboring bodies 101. When fully deployed, they form a protective roof or cover over the agricultural field. This temporary canopy structure serves as a barrier against falling rocks, gravel, or soil debris, effectively minimizing physical damage to the crops and the field’s irrigation or infrastructure. This is particularly important in step-farming areas where the crop beds are often exposed to overhanging slopes or rocky ridges above them. For example, during a minor landslide triggered by rainfall or tremors, rocks might tumble down the slope directly onto the cultivated terrace below. In such scenarios, the triangular members 105 act as a deflection shield, absorbing and redirecting the impact away from the delicate crops beneath.

[0055] To ensure that this shielding means is not only effective but also resilient, each triangular member is constructed with a dual-layered structure, a first (outer) layer and a second (inner) layer. These layers are interconnected via a plurality of springs 106, which serve as shock absorbers. When rocks or debris strike the canopy, the force of the impact is distributed across the surface and dampened by the springs 106, thereby reducing the risk of puncture, collapse, or rebound. The inclusion of springs 106 between these layers not only helps absorb shocks but also allows the structure to flex slightly upon impact, thereby avoiding breakage or long-term damage.

[0056] To illustrate, consider a real-world scenario where a moderate earthquake of magnitude 4.5 strikes a hillside village. The seismic sensors embedded in the hydraulic bodies 101 detect ground tremors that potentially dislodge boulders from nearby cliff edges. In response, the microcontroller triggers the rapid deployment of the triangular canopy, which unfolds within seconds. As rocks begin to fall, they are intercepted by the spring-cushioned canopy, which absorbs the kinetic energy and safely disperses it across the structural frame. This quick deployment not only saves the crops from being crushed but also prevents soil disruption and costly replanting efforts. Additionally, the triangular members 105 are developed to return to their original retracted position once the danger has passed, either through automated retraction via the motorized hinge or manual reset by farm personnel.

[0057] One of the most crucial challenges in hilly agricultural terrains is soil erosion, which not only diminishes the fertility of the land but also leads to landslides, root exposure, and destruction of crop yield. To address this persistent issue, the device includes a soil anchoring means. An L-shaped rod 107 is integrated into one of the hydraulic bodies 101 stationed at the corner of the field to provide both vertical and rotational movement, which is crucial for operating in rugged or uneven terrain. Mounted on this rod 107 is a hydraulic shaft 108, which is the primary actuator responsible for the insertion of a soil anchor.

[0058] The hydraulic shaft 108 is attached with a sun and planetary gear arrangement 109 which is composed of multiple motorized planetary gears housed within a toothed ring. Each of these planetary gears is connected to the L-shaped rod 107 via L-shaped bars, allowing them to rotate in synchrony. At the center of this arrangement 109 lies the sun gear, which is directly connected to the hydraulic shaft 108. When the L-shaped rod 107 is rotated (upon command from the microcontroller), the connected L-shaped bars rotate the planetary gears. These planetary gears then rotate the central sun gear, which in turn rotates the hydraulic shaft 108. This configuration ensures high torque transfer with minimal energy loss, making it suitable for penetrating hard or rocky soils, which are commonly found in hilly areas.

[0059] To initiate the anchoring process, the microcontroller first commands a robotic arm 110 also configured on the same hydraulic body 101 to access a storage chamber 111 attached to the body 101. This chamber 111 securely holds soil anchors, which are specialized tools resembling heavy-duty spikes or screws, designed to pierce through layers of soil and lodge themselves deeply to provide anchoring support. The robotic arm 110 fetches a soil anchor and positions it into a motorized clamp 112 mounted on the hydraulic shaft 108.

[0060] Once the anchor is secured in place, the microcontroller activates the hydraulic shaft 108. Simultaneously, the L-shaped rod 107 is rotated, which drives the entire sun and planetary gear arrangement 109. This rotation is converted into vertical insertion motion of the shaft 108 due to its hydraulic nature, effectively drilling the anchor into the soil. The combined effect of rotational torque and downward thrust ensures that the anchor is deeply embedded into the soil, thus providing maximum grip and resistance against shifting soil layers.

[0061] This is especially beneficial in step farming, where multiple terraces are carved into a hillside. In such setups, the integrity of each step is vital to prevent cascading erosion. For example, during heavy rainfall, water start washing away the topsoil from the higher terraces. By embedding soil anchors at strategic locations such as the edges of each terrace or near water runoff paths the bodies 101 stabilize these vulnerable areas. The anchors act as reinforcement pins, holding the soil layers intact and minimizing the risk of collapse. The anchors are removed and reinserted if needed, and the force applied is varied based on soil type and moisture content, which the microcontroller assess using sensors. Furthermore, since the entire operation is automated and governed by the microcontroller, it requires minimal manual intervention, allowing for continuous field protection even in the absence of farm workers.

[0062] In agricultural environments, especially in hilly terrains, rainwater accumulation poses a significant threat to crop health and structural elements within the field. Standing water on protective structures lead to added weight, material fatigue, and in the worst cases, structural collapse, particularly if these structures are intended to shield crops from falling debris or animals. Moreover, accumulated water becomes a breeding ground for pests, fungal growth, and root rot, especially in fields with limited drainage infrastructure. To address this issue, the present invention incorporates a highly responsive and automated rainwater mitigation process, which includes a set of V-shaped units 113 installed between adjacent hydraulic bodies 101 that frame the field.

[0063] Each of these V-shaped units 113 is constructed from lightweight yet durable materials, which include but not limited to such as treated aluminum or reinforced polymer composites, designed to withstand constant exposure to outdoor conditions. Their geometric configuration with a central channel sloping downwards in a "V" form is inherently suited to channel rainwater away from flat or concave surfaces. These V-shaped units 113 are not fixed in place; rather, they are adjustable by means of a motorized pivot joint 114 located at the connection points between each V-shaped units 113 and the adjacent hydraulic bodies 101.

[0064] A rain sensor is affixed to one of the hydraulic bodies 101 that is ideally positioned in an open area of the field to ensure immediate exposure to atmospheric moisture or the first droplets of rainfall. This sensor continuously monitors environmental conditions, and upon detection of rainfall, sends a signal to the microcontroller. In response to this input, the microcontroller immediately sends an activation signal to the motorized pivot joint 114. These joints allow each V-shaped unit to tilt along its axis, altering its angle so that water no longer pools on its surface. Instead, the rainwater is channeled downward and away from the V-unit’s surface via gravity, either onto the ground where appropriate drainage channels exist.

[0065] For example, in areas like the Himalayan foothills or the Western Ghats, regions known for their step farming and high monsoon rainfall, the accumulation of water on protective field covers result in cascading structural failures. The tilting V-units eliminate this risk by preventing stagnation and allowing water to flow off smoothly as it lands. The motorized pivots are also configured with multiple tilt angles, allowing the device to adapt based on rainfall intensity. For example, during a light drizzle, the tilt angle is moderate, while during a heavy downpour, the angle is increased to ensure rapid runoff.

[0066] Furthermore, these V-units are coated with hydrophobic materials, allowing water to bead up and roll off more effectively. This also reduces the accumulation of dust and debris, maintaining their transparency and functionality over time. In real-world practice, this serves not just as a water control feature but also as a multi-functional protection layer for the crops. For example, during a sudden mountain downpour, while seismic sensors and triangular shock-absorbing members 105 protect the field from rock fall, the V-units ensure that no rainwater pools on top of these structures, thus preventing any weight-related failures.

[0067] In addition to physical deterrents, sound-based animal repellents, and structural barriers, the bodies 101 are installed with a fragrance-based animal deterrent means that enhances its effectiveness against a wide range of wildlife commonly found near hilly agricultural fields. This is composed of a multi-sectioned container 115 securely mounted on one of the hydraulic bodies 101 installed at the field’s perimeter. The container 115 is subdivided into multiple sealed compartments, with each section pre-filled with a specific type of fragrance solution, customized to repel different categories of animals. These include pungent organic compounds such as peppermint oil, predator urine simulants, garlic extract, or citrus-based solutions, which are well-documented for repelling herbivores like deer, wild boars, and even smaller pests like rodents. Each section of the container 115 is connected to a dedicated electronic nozzle 116, which aids in the dispersion of the fragrance solution.

[0068] Each nozzle 116 is equipped with a motorized swivel joint 117 at the base that enable the nozzle 116 to tilt and rotate multi-directionally, thus ensuring that the sprayed solution covers a wide radial area surrounding the field. This is particularly important in hilly terrains where wind directions shift rapidly, and uneven land gradients limit the effectiveness of unidirectional sprays. When an animal is detected in proximity to the field, the microcontroller not only identifies the type of animal through database referencing but also determines the most suitable fragrance deterrent to deploy based on pre-fed behavioral data associated with that species.

[0069] For example, in the event that a wild boar is identified near the field edge, the microcontroller activates the nozzle 116 containing predator urine scent or spicy pepper solution, which is known to deter boars due to their acute olfactory sensitivity. Conversely, if deer are detected, the controller trigger the spray of garlic or rotten egg-based solutions, which mimic spoiled vegetation and discourage grazing behavior. The selected nozzle 116 then pivots and begins to disperse the solution in a mist or fine spray form, propelled either by a compressed gas or a micro-pump embedded within the nozzle 116. The directional control ensures that the spray is targeted toward the location of the animal or covers a wider area when multiple animals are detected.

[0070] In a practical deployment, such as on a step-farming field in the Himalayan ranges, this fragrance spray serve as the first line of deterrent before physical barriers are even activated. Upon detection of movement and odor consistent with grazing animals like Himalayan tahr or barking deer, the microcontroller initiates a low-energy, targeted spray, minimizing the need to raise net 102 or trigger other deterrents unless the animal continues to approach.

[0071] To further enhance the adaptability and environmental responsiveness in hilly terrains where dust storms and wind-blown soil particles are common, the device incorporates a dust detection and electrostatic mitigation. This is crucial for preserving the health of crops, especially in semi-arid or mountainous regions where loose topsoil and unpaved trails frequently lead to suspended particulate matter being carried into cultivated fields. Each hydraulic body 101 is equipped with a dust sensor, which continuously monitors the air quality and presence of dust particles in its immediate surroundings. These dust sensors operate on optical scattering principles or laser-based particulate detection, offering real-time analysis of dust density in the environment.

[0072] When an elevated level of dust is detected such as during a dry wind event, post-harvest tilling in nearby fields, or vehicle movement on adjacent rural roads, the sensor sends this information to the microcontroller that centrally manages all field protection functions. In response, the microcontroller initiates a countermeasure by activating an electrostatic generation unit 118 associated with each of the collapsible net 102 that connect the adjacent hydraulic bodies 101. This net 102, which are normally stowed or deployed depending on animal presence, now serve an additional role as dynamic dust filtration barriers. Each net 102 is constructed from a grid of links making them suitable for electrostatic charging.

[0073] Upon activation, the electrostatic generation unit 118 induces a static electric charge across the net 102 surface, essentially turning the deployed net 102 into an electrostatic air filter. This creates a charged field around the net 102 structure, causing dust particles typically carrying neutral or opposite charges to be attracted and trapped on the net’s surface. This is particularly useful in high-altitude fields or areas undergoing infrastructure development where airborne dust reduces photosynthesis efficiency, block plant stomata, and lead to poor crop health. By intercepting the dust at the perimeter before it settles onto crops, the device helps maintain a cleaner microclimate within the cultivated field.

[0074] For example, consider a scenario in a hilly village located along a dirt road frequently used by tractors and local transport. On a dry, windy afternoon, vehicle activity generates clouds of dust that drift toward terraced crop plots. In this instance, the dust sensors detect the spike in particulate levels and immediately signal the microcontroller, which then energizes the deployed net 102. As the charged net 102 start to attract the dust particles, a significant portion of the airborne material is captured electrostatically, clinging to the net 102 surface rather than dispersing over the crops. This reduces the need for water-intensive post-dust cleaning methods or manual dusting of leaves and produce, thereby saving both time and resources.

[0075] Lastly, a battery is associated with the device to supply power to electrically powered components which are employed herein. The battery is comprised of a pair of electrode named as a cathode and an anode. The battery uses a chemical reaction of oxidation/reduction to do work on charge and produce a voltage between their anode and cathode and thus produces electrical energy that is used to do work in the device.

[0076] The present invention works best in the following manner, where initially, the set of hydraulic bodies 101 is installed at the corners of the field, each interconnected via collapsible net 102 formed from crisscross-arranged links in stowed configuration. The thermal imaging sensor 103 paired with electronic noses detect heat signatures and odors emitted by approaching animals. This sensory data is processed by the microcontroller, which accesses internal animal classification database to determine whether the approaching entity is predator or herbivore. Upon confirmation, the microcontroller activates hydraulic units in the corner bodies 101, causing them to extend and deploy the collapsible net 102 by separating the links through pin-joint-based articulation, thereby forming secure perimeter along the terraced or uneven edges of the hilly field.

[0077] Simultaneously, speakers 104 integrated within the bodies 101 emit species-specific deterrent sounds based on the detected animal’s profile. In parallel, if seismic sensors detect land tremors, the microcontroller commands motorized hinges at the apex of each body 101 to tilt and deploy triangular shock-absorbing overhead panels made from two layers connected by springs 106 to shield crops from falling rocks or debris. During soil destabilization events, the microcontroller commands to deploy soil stabilization means, wherein the robotic arm 110 fetches soil anchor from chamber 111 and positions it onto motorized hydraulic shaft 108 powered via sun and planetary gear arrangement 109, inserting the anchor into the ground to prevent erosion.

[0078] In continuation, on detection of rainfall using rain sensors, the microcontroller actuates V-shaped panels via motorized pivot joint 114 to tilt and drain water, preventing accumulation on protective surfaces. Complementing the deterrence strategy, the microcontroller also activates multi-sectioned fragrance container 115, selecting and spraying specific type of scent via motorized swivel nozzle 116 in multiple directions to repel animals through olfactory stimuli. In dusty conditions, dust sensors trigger electrostatic charging unit that energizes the deployed net 102 to attract and trap airborne dust, preventing its intrusion into the field.
